a broiler, and has for its primary object a broiler which can be usedout of doors and the efliciency- `trary will be increased by the wind.VlIereto-fore the presence of wind has proven to be a great drawback toout-or-door broiling, and food so treated is not satisfactory.

A further object of this invention is avbroiler adapted for the use ofcharcoal and so constructed that an even fire can be maintained over theentire bed and the steak or other food be evenly b-roiled throughout.V

-These and other objects will appear from an examination of thefollowing description and of the drawings which form aV part thereof,and

in which: f Y

Fig. 1 is a perspective View of a broiler embodying one form of thisinvention;

Figs. 2 and 3 are enlarged cross sectional views thereof taken along thelines 2-2 and 3-3 respectively in Fig. 1;

Fig. 4 is a plan view of a broiler embodying another form of thisinvention; and

Fig. 5 is a side elevation thereof partially in section. l y.

Inthe embodiment shown in Figsfl, 2 and 3 the'broiler I0 comprises ahousing II in which are suitably supported grates I2 and I3 andaremovable ashdrawer I4. The wall I5 of the housing is preferablyinsulated in any suitable manner to prevent the escape of heat, 'and'the back wall has a plurality of holes I6, here shown as arranged in arow near the lower edge thereof. The grates I2 and I3 are supportedwithin the housing upon a removable standard, which comprises posts I1connected at the top by a bar I8 at each end and an angle bar I9 at eachside. The posts Il' are further connected at each side by a second anglebar 20, parallel to the rst and secured to the posts substantiallymidway of their length. The grates I2 and I3 are removablyV supportedupon the bars I9 and 20 and the space between is enclosed by a wallconsisting of splates 2l and 22 xed in place in any suitable manner.Guide blocks 23 at the corners of the housing engage the posts I1 andposition the standard from the walls I5 of the housing to define achannel 24 for a purpose to be set forth '5 below.

The ash drawer I4 enters the housing I-I through a hole 25 in the frontwall thereof, and is positioned in the housing between angle bars 26 onthe bottom plate of lthe housing. The

.front wall 21 of the drawer isofsuch 'size` that v p v 1 1c1aims.(orgiasgay This invention relates `to an improvement in whenY thedraweris closed thehole 25 is sealed thereby and 4its back 4wall' 28 bearsagainst the backwall ofthe vhousing to vseal the holes I6 therein (SeeFig. 3). A suitable handle 29 facilitates the manipulation of thedrawer.

In'using this .broiler the fuel, preferably charcoal, is placed withpaper or other kindling material on vthe grate I3 and the kindlinglighted. For; convenience the space dened by the grates I2 and I3 andthe Vplates 2l and 22 will bereferred toY as the fire box. The drawer I4is at rst partially opened, as shown in dotted lines inFig. 3,so thatair enters the compartment 30 'at the bottom of the housing below the rebox'throughthe holes I6 and the opening 25. This provides a 'draft whichfacilitates the kindling ofthe fuel. When vthe fuel is well ignited thedrawer I4 is closed, whereupon a secondary draft isset up in accordancewith the well known principle down the channel 24 formed between thewallof the standard and that of the housing, and then upwardly through thefuel. As shown in the drawings, the plates 2| and 22 are perforate andhence some of the air flowing down the channel enters the fire boxthrough the perforations and 'thus provides a more even firing of -th'efuel sof=that the entire surface is ignited. Undersome Aconditions,however, this further draft is not essential and imperforate plates maybe -'employed.=`=l The steaks or other food to be broiled are placed onthe upper grate I2.

The ashes fall through the lower grate I3 into the drawer I4. Each grateis preferably made in two sections which meet at the center when placed'on the angle bars I9 and 20. The sections -of the lower grate I3 mayterminate in tongues 3| which are narrower than the spaces between theposts I1, so that these sections may be separated at the center topermit quickly cleaning the grate.

Figs. 4 and 5 illustrate a portable broiler 40 embodying another form ofthis invention comprising an annular housing 4I open at the top andbottom, a fire box defined by an annular WallV 42, and grates 43 and 44and a handle 45. The grates are of the same conformation, each having aplurality of spaced tongues 46 having the outer edges outwardly andupwardly tapered. The lower grate 44 is supported Yupon a corrugation4-1-formed in the wall of the housing 4I. The'wall 42' is' formed by aplate which rests upon the tongues of the grate 44 and is spaced fromand secured to the housing wall by bolts 48 and sleeves 49. The tonguesof the upper grate .rest upon andy are supported by the upper edge ofthe wall 42. In the wall 42 below the corrugation 41 are formed aplurality Iof holes 50 through which air may enter the compartment 5l ofthe housing below the fire box. Surrounding the lower portion of thewall 42 is a band 52 having holes 53 therein. Ihe band is rotatable asby means of a projecting handle 54, so that in one position the holes 53register with the holes 50 and in another position are out of register,so that the holes 50 are sealed.

The housing wall and the wall 42 are spaced apart to provide an annularchannel 55 which leads into the compartment 5I of the housing.

As in the iirst described embodiment the fuel is placed on the lowergrate 44 and the steak or other food to be broiled is placed onvtheupper grate 43. The fuel in the fire box is kept burning at the desiredrate by means -of the draft through the holes 50 as regulated by theband 52 and the draft which flows downwardly in the channel 55 andupwardly through the fuel. When, as here shown, the plate forming thewall 42 is perforate, some of the air flowing downwardly in the channel55 enters the iire box through the perforations in the plate, and passesover the fuel. As in the other embodiment, the plate may, if desired, beimperforate.

It will be noted that in each embodiment a draft is set up by air drawndownwardly into the compartment at the lower part of the housing andthen upwardly through the fuel, which may be supplemented when desiredby air admitted directly into such compartment of the housing. Inaddition, when the wall defining the fire box is perforate, some of theair is drawn over the fuel or through the sides thereof. When the directentry of air into the housing compartment through the wall thereof iscut oii', the draft downwardly through the channel is set up solely bythe heat rising from the fuel bed. The amount of air drawn downwardlythrough the channel varies according to the draft required to maintainthe fire.

While two embodiments of this invention have been shown and describd, itwill be understood that I am not limited thereto and that the form andconstruction of such embodiments may be altered and that otherembodiments may be made, all without departing from the spirit and scopeof the invention as set forth in the following claims.
